The present invention pertains to a novel window construction designed particularly for household use although suitable for other uses as well. 7

The principal object of the invention is to provide a window of the sliding sash type, and yet capable of being swung on a vertical axis inwardly of a room for cleaning purposes. Such adjustability of the window prelo vents the well known difiiculties at present experienced in washing windows of the sliding sash type.

In keeping with this object, the sashes are so mounted that at least one vertical edge 1 thereof is capable of a swivel movement with respect to the window frame. One edge of each sash is thus adapted to be swung entirely out of the frame, but is normally pre vented from being swung by means of a i" molding strip attached to the frame. hen

it is desired to swing the sashes for the purpose of cleaning them, the moldings are detached.

A further object of the invention is to pro- 3 vide means for supporting the sashes in the frame and preventing tiem from dropping when swung out of the frame. This means consists of latches carried by the sashes and adapted to enter grooves in the window frames when the sashes are initially swung.

The latches are so constructed that after subsequent swinging of the sashes, they remain slidable in the grooves but cannot be withdrawn therefrom until the sashes are re- 1 turned to normal or closed position.

A still further object of the invention is to provide an e'li'ective seal to prevent undesired leakage of air through the window structure, and also provide air pockets longitudinally of the sashes at the rounded ends.

The invention is fully disclosed by way of example in the following description and in the accompanving drawings, in which Figure 1 is a plan section;

Fig. 2 is aplan section showing the sashes in elevation;

Fig. 3 is a detail plan section showing the sashes turned at an angle;

Fig. 4 is a detail vertical section;

Fig. 5 is a detail perspective view;

Fig. 8 is a sectional perspective view showing the keepers;

Fig. 9 is a sectional perspective view at the other side of the window frame;

Fig. 10 is still another sectional perspective view.

Reference to these views will now be made by use of like characters which are. employed to designate corresponding parts throughout.

In Figures 1 and 2 is illustrated a window frame consisting of frame sections 1 and 2 fastened together at a tongue and groove joint 3. This joint stiffens the sides of the frame. In the frame sections 1 and 2 are formed vertical, arcuate grooves 4L and 5 respectively at both sides for the purpo"e of receiving window sashes 6 and 7 respectively slidable therein. The ends of the sashes are rounded as at 8 to fit properly in the grooves and also to be swung on a vertical axis as will presently appear. Between the sashes are provided molding strips 9 and 10 suitably shaped for engagement by the rounded ends 8. At the inner side of the sash 7 are also provided moulding strips 11 and 12 which hold the sash in position.

The strip 12 is severed approximately midway between its ends as indicated by the numeral 13 in Fig. 9, thereby providing a removable lower section 12 normally held in position by a screw knob 14. In like manner the intermediate molding strip 10 is also severed between its ends as indicated by the numeral 15 to provide a removable lower section 10 as shown in Fig. 9. The section 10 carries a plate 16 having offset ends 17 as shown in Fig. 5. These ends are receivable in a curved bracket 18 as shown in Fig. 10.

On the top of each of the sashes 6 and 7 is secured a plate 20 formed with a longitudinal boss or sleeve 21. Since these members are alike on both sashes, only one of them need be described. In each of the bosses is mounted a slide or latch 22 having at its outer end a locking head or lug 23 and at its inner end a finger piece 24. The groove bracket-s l and 5 at this side of the window frame are grooved transversely at (Figs. 2 and 3), and the grooves are of sufficient height to receive the locking heads 23. However, in the normal or closed position of the sashes as illustrated in Fig. 2, the heads are not in line with the groove and cannot be inserted therein.

Over the grooves is secured a plate 26 having slots 27 disposed over the grooves 25 and of less height than said grooves. One end of each slot, however, has an enlarged entrance or mouth 28 of sufiicient size to receive the corresponding locking head 23.

In the operation of the device as thus far described, let it be assumed that the lower sash 7 is to be swung on a vertical axis into the room in order that both sides thereof may be washed. The lower detachable section 12 of the molding strip 12 is removed, whereupon the right hand end l) of the sash 7 may be swung away from the window frame. If the swinging movement were carried out to any considerable extent, there would be nothing to support thissash in the window frame. It will be seen, however, that a slight turning movement of the sash 7 b ings the locking head 23 thereof into register with the enlarged mouth 28 of the coresponding slot 27. At this time the latch 2 is moved to insert the locking head 23 in the mouth 28, and continued swinging of the sash 7 brings the head 23 in the groove 25 behind the plate 26. The locking head is thus brought behind the narrower slot 27 and consequently cannot be released from the window frame until the sash is returned to its normal or closed position.

In order to swing the upper sash 6 in like in anner, the lower sash 7 is first swung in the manner described, after lowering the sash 6, and the removable section 10 of the intermediate molding 10 is now withdrawn. It will be seen by an examination of Figs. 5 and 10 that the plate 16 may readily be withdrawn from the bracket 18 for this purpose. The slide 22 on the upper sash (i now cooperates with the corresponding slot 27 and groove 25 in the manner already described in connection with the swinging of the lower sash.

The plate 26 is formed between its ends with a pair of horizontally curved ears 30 similar to the curved ends of the bracket 18 previously described. The intermediate molding 9 at the left hand side of the frame may also be severed midway between its ends as at 31 (Fig. 7) to provide a detachable lower section 9. This section carries a detachable plate similar to the member 16 adapted for locking engagement with the ears 30. The removable section 9 may be withdrawn whenever desired to permit turning of the sash 6 on its right hand end or to completely remove this sash if desired or neces sary.

The plate 20 on the lower sash 7 is formed with a transverse boss 35 accommodating a sliding bolt 36. This bolt is adapted to enter an aperture 37 in the upper sash 6, as shown in Fig. 6, to lock the sashes together and thus lock the window in closed position.

At the rounded end, the sashes 6 and 7 are grooved longitudinally as at 38 to form air pockets 39. The ends of the sashes being rounded as at 8 to fit properly in the grooves 4 and 5 provide effective seal and prevents undesired leakage of air through the window structure. In the event of undesired air entering from both sides of the window, air pockets 39 will serve as mixing chambers for both air jets of different temperature. Undesired cold air draft from the outside is thus prevented.

For the purpose of reinforcing or stiffening the sashes 6 and 7 rigid metal strips 4! are passed vertically therethrough at the rounded ends as clearly shown in Figs. 1 and 4.

The sashes are balanced by sash weights, and from one of the weights extends a cord 42 secured to the right hand side of the lower sash 7 in the usual manner as indicated by the numeral 43 in Fig. 9. The cord 44 at the other side of the sash is anchored to an eyelet 46 formed as an integral part of the boss 21.

As stated in the introduction to this speciiication, it will be seen that the invention :3

provides a durable window of the sliding sash type wherein the sashes may also be swung on vertical axes for cleaning purposes. Moreover, the construction enabling such swinging is simple, secure and effective. It

will also be seen 1;; reference to Fig. 2 that, because of the fact that the outer sash is narrower than the inner sash, the window opening diverges into the room and thus forms a diverging and increasing shaft of light entering the room from the exterior.
